Like other volumes in the series Issues in Political Theory, which Weale edits with Peter Jones, this book combines an overview of the topic suitable for advanced undergraduates and above with an original argument reflecting the author's distinctive perspective that is likely to stimulate fellow specialists. The combination is an attractive one, which, when it works—as it does in this case—ensures that we do not get the sort of deadly dull textbook that merely rehashes other people's ideas. There are two novel features of Weale's argument. The first is his justification of democracy in terms of its capacity to enable members of society to advance their common interests as political equals in a situation of human fallibility. The second is his attempt to delineate the form of democracy, including the type of representation and decision rule, most likely to promote this purpose. I take each in turn.
